what number does the mad hatter have on the side of his hat?

The Mad Hatter from Lewis Carroll’s “Allice in Wonderland” is eccentric, to say the least. The character’s name came from the saying “mad as a hatter.” Making hats used to involve the use of mercury, which was highly toxic. A hat maker suffering from mercury poisoning would often exhibit strange and anti-social behavior.

The Mad Hatter that Alice meets has a slip of paper on the side of his hat that reads “In this style 10/6.” “10/6” is a price of ten shillings sixpence. The slip of paper is either an order for a hat the Mad Hatter is supposed to make for ten shillings sixpence, or is an advertisement offering to make a hat “in this style” for that price. In the Disney animated version of the story, the slip of paper reads simply “10/6.”

In March 2012, the television series “Once Upon a Time” featured a mad hatter named Jefferson in the episode “Hat Trick.” The series is heavily steeped in classic fairytale characters.
